Modeling and Optimization of RMS Pulse Width for Transmission in Dispersive Nonlinear Fibers

Open Access Open Access

Abstract

Simple algebraic expressions are derived to approximate the optimal input RMS pulse width and the resulting output RMS pulse width in single-mode fibers. The results are compared with the previously published methods and with numerical results by the split-step Fourier method. In addition, for a transform-limited Gaussian input pulse, it is shown that there is no optimum input pulse width to minimize the output spectrum width. Finally, with fiber nonlinearity, it is shown mathematically that there is not an optimum input pulse width to minimize the product,<TEX>${\sigma}_t{\sigma}_{\omega}$</TEX>, which is inversely proportional to the transmission capacity of WDM systems.
